BELT-FA'STENER.

SPECIFICATION formingpart of Letters Patent No. 587,025, dated July 27,1897. Application filed 11 23, 1896. Serial No. 596,591. (No model.)

To all whom it may concern.-

Be it known that I, DESIDER VON VITAL, a subject of the Emperor ofAustria-Hungary, residing in the city and county of Philadelphia, Stateof Pennsylvania, have invented a new and useful Improvement inBelt-Fasteners, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of abelt-fastener constructed of parts, as will behereinafter set forth.

Figure 1 represents a top or plan view of a belt-fastener embodying myinvention. Fig. 2 represents a longitudinal section thereof. Fig. 3represents an end view thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a frame formed of the cross-barsB and side plates 0. Pivoted to said plates 0 are jaws D, which extendparallel with the cross-bars B and are adapted to move to and from thesame. On the faces of each bar B and the adjacent jaw D are spurs E andF, which The spurs F on each of the jaws D are nearer to the axis of thesame than are the spurs on the cross-bars.

It will be seen that each end portion of a belt is bent on itself, onelength being passed between the cross-bar and jaw and the other lengthrested against the under side of said jaw, the bend of the belt being atthe back of the jaw as a bite and the strain or draw being on the underlength and from the jaw.

It will be seen that the jaws are forced toward the cross-bars and theend portions of the belt held tightly in position by the pressure ofsaid parts, so that slipping of the same is prevented.

The ends of the side plates 0 are extended beyond the axes of the jaws,forming lips G, which when the jaws are closed cover the sides of thelatter to prevent any possible lateral displacement of the belt and actas guards to receive the thrust of the jaws should they be subjected tolateral strain.

It will be readily understood that the devicecan be quickly adjusted andthat by using the fastener there is no necessity of punching-holes inthe belt; but if the latter has holes before the fastener has beenapplied it will not prevent the use of said fastener and the belt is inno way weakened.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A belt-fastener consisting of the two side
